Gravitational waves are like the echoes of a cosmic scream. Imagine two giant space rocks, black holes, crashing into each other. They shake space-time, and that shaking travels outwards like ripples on a pond. We can feel these ripples here on Earth using special machines called detectors.
Examples
- Imagine two black holes circling each other like dance partners, when they finally crash together, the whole space around them ripples outward.
- These ripples are so tiny that we need super-sensitive machines to feel them.
